,A Toalll wiom t may concern Be it known that we, JOSEPH Goomno'uun and HARM' HALLAM, subjects of the King of England, residing at Leicester, Leicestershire, England, have invented certain Improvements in yh/iachines for Attaching Welts or Randsto Stock, of which the following description, in connection with the laccompanying drawings, is a speciticatifm7 y tuator into operative relation to the slitting like reference characters on the drawings indicating like parts in the several figures.

.This invention relates to machines for attaching welts, rands and s1m1lar strips `of 'material to stock in the manufacture of boots and slices, and more particularly to machines l'for this purpose which embody mechanism for slitting the inner margin o'f the. strip to render vthe strip more flexible whereby it may be conformed more easily to the outline. ofthe edge of the stock during the attachment of the strip to the curved portions of the stock.

An object of the invention is to improve the organization of the machine as a whole, particularly with respect to the means for j controlling the starting and stopping of the machine, -the presentation of the work to the machine and the operation of the slitting' mechanism.

-In machines of the type referred to, as heretofore constructed, the raising of the Work support, the starting of the, machine` and the throwing into operation of the strip slitting mechanism have each been controlled by 'a separate treadle or hand lever; and one feature of the present invention is a simplified construction of the machine whereby two or more of the said operations may be controlled by a single manually op-l erable part.

In the illustrated preferred embodiment of the `invention a single manually operable part controls not only the operation of thc strip `slitting device but also the clamping of the work and the starting of the machine. rIhe arrangement is preferably such that by means of the said manually operable part the strip slitting device may be thrown into or out of action at the will of the operator after the said part has c'lfected the starting' of the machine or has effected first the clamping of the work in, or its movement into, operative position and then the startingry of the machine. In the illustrated construction, the manuallyr operable part has a lost motion connection with the starting and stopping' means, is arranged to operate a calm of which the function to raise and lower the work support into and 'from operative position, and is connected with a reciprocating actuator of which the path of movement can be shifted by the said manually operable part so as to bring the acdcvice when that device is required to be operated.

The invention also aims to provide improv ld slitting?r mechanism so arranged with respect to the mechanism for inserting the attaching` 'l'asteniugs that by its operation it will facilitate the attachment of the strip to the work, :ntl that the cooperation of the two mechanisms will result in an improved quality ot'worlt. l`o this end another feature of the invention is the provision in a machine for sccucinpv wells, rands or similar strips. of material to stock in thc manufacturc of boots` and shoes of slitting` mcchauism counn'isinp a knife or cutter ar tinged lo slit the inner edge of thc strip by entering; the under surface of the strip, that is, the surface which is in contact with the stock when thc strip is attached thereto, and moviu;4 obliducly through the strip in such direction that in securing' the said strip to the stock b v successive operations of the fastelling` insertingmechanism each slit portion will, before being secured, override the p0rtion immcdiatchr in front of it that has already been 4attached to the stock.

These and other features of thc invention including certain details of construction and combirmlions ol' parts will be described in connection with an illustrative n'iachinc and pointed out in the appended claims.

Referring now to the accompanying drawings,-Figt1re l is a front elevation of a portion of the head of a machine for inserting fastenings in which the present invention is embodied, part of thc table supporting mechanism being shown in section; Fig. Q is a side elevation, certain parts of the clutch actuating` mechanism being shown in section; and Fig. 3 is a perspective of the heel portion of a sole to which a rand has been attached by the machine shown in Figs.

tionis" shown as embodied'in a fastening A'inserting machine of the kind described-and illustrated in United States Letters' Patent Ato L. Goden, no. 490,625'- and to L. A. Casyac grain,`N'o. 611,405, to which Letters'Patent reference' may be hadl, for 'a more. detailed description off arts herein illustrated but 4not fully described, such description being unnecessary for afcomplete, understanding ofthe invention of thispapplication.

The nose l in which operates a driver 3 carried by a' driver bar 5, the o'scillatinglevver-:7 carrying the movable cutter of the fasteningl severing mechanism and 4held in .a plurality of tapered nails and to drive the nails one .by one through the welt and into the stock as said stock and welt are fed past the nose 1.

' Beneath the nose `1` is 'a table-13 -for supporting the pieceof stock A, a guideway 15 being arranged above the table to guide a welt B, preferably tapered at its inner margin as shown in Figs. 1 and v2, into position on the piece of stockthus supported. As lwill hereinafter appear' thetable 13 is capable of being rotated and ,is pressed upward yieldinglyv byV a spring so as to clamp-the stock and the welt between itself andthe A feed Wheel 11' whereby the lstock and weltv will be fed under the fastening inserting mechanism and secured together. Rotation ofthetable is effected as in' the machine of Letters Patent No.- 611,405, byvmeans of a long pinion 17 which meshes with the gear 19 integral with the table.l During the operation ofthe machine the` stock and welt.l

. are held between thevworkl table or support 13 andthe feed Wheel 1l as has .been described, the slitting o f theinn'er margin'of the welt is effected when-desired by'a knife 21, and power is applied to the machine through a clutch of 4any convenient form such as that shown in the'Letters- Patent rel,V

u 1 ferred to'fabove, said clutch beingzco'nnected i with the actuatingrod 23.

In machines of the present type as hereto-v fore constructed. the throwing in of the clutch to start the machine, the gripping of y the stock andwelt between the feed wheel and the'work support, and the' throwing into operation of the slitting'y mechanism have each been .controlled by aseparate means.

, In order, however, to facilitate control of the v'several mechanisms referred to, the 'follow'- ing construction yand arrangement of parts'is .employedzlA- treadle25 is connected by a" v.same time'vr freev Ato rotate.

meines rod 27 with a lbell crank-lever 29- havingtrunnions 31 mounted in an'extension 33 of! I the machine frame. One arm of the belli' crank lever is provided with 'a cam 3T withf' .which a roll 39. carried in' a sleeve 41v is kept in contact by a spring 43 whichbears at its Alower end against a washer 45 supported on;l

the. sleeve 41 and at its upper end against'a second washer r47 which abuts the under side' .1

of a bearin l49 projecting from the frame' of the machine. |The sleeve 41- is adapted to slide .within a boss on the extension 33. of theframe -when actuated by the; cam 37, and the washer'45 supports secondxspring 51 locatedv within the spring 43.4 Upon tlie'upper end of the-spring 5l rests a washer-,53 i.y

which in turn Supports a tubular ertensionV of the table 13, 'said extension 'being' loosely mounted in the bearing 49. A rod 57, which at its upperV end 4is threadedinto the table or support-13, is slidingly mounted .in the sleeve 41 and-lis provided with.l a heady which servesas a" stop'to limitits upward movement.A Withthis construction the'rol-le'r 39 is at all times held bythe act-ion of the spring in contact with thecam on the armof the bell crank level-29'; and, when the'rollerl lis raised, the stock is held yieldingly'a-gainst served in Fig. 2,` 'the caml 37 is proi-ided-y with a raised portioiifor the purpose of rais-` ing the work' table 13 into yielding contact with the Work upon theirst step'in the dei l Ipression of the t'readle 25, and this raised portion of the' cam' is concentric with the axis- 1' of the. trunnions 31 so that the table. .will remainstatio-nary as regards its heightvor' pressure on the stock upon further depres-A sion of the treadle,- said further vdepression lbeing adapted, as will presently be described,` first to operate the ,clutch mechanisml for applying power to 'the-machine andv there'- afterto bring theslitting'device.into opera-1i' i o Lfii'of '.For the purposeY of operating the clutch mechanism the treadle 25 isconnectedby a tion.

rod`59,.lp ivoted to the'treadle at 61with the clutch actuating rod 23; and the rods 59 and 23 are provided with a lost/motion con-"- nection whereby, before `the rod 23 4 is actuated, the treadle 25 is permitted sulicient- 'downward movement to 'raise the table 13 ,in the manner which has been described above. f v

spring 1 whichengages at its upperen um enlargement 73.011 said rod and ai its lower .downward movement of the treadle will throw in the clutch to sta rt the lnachine. It will be noted, however, that after the clutch has been thrown in, the spring'67 will permit still further downward movement of the treadle. 4

For the purpose of controlling the actuation ofthe slitting mechanism by the nal step of the depression of the treadle 25 an arm 7 8 is secured to one of the trunnions 31 of the bell crank lever Q9. This arm 78 bifurcated. and carriesa transversely mounted, angularly movable pin S2 through which loosely7 passes a rod S1, said rod being con necte and a spring 83 with the arm 78 and at its upper end with one arm S5 of a bell crank lever mounted to turn in bearings in the frame of the machine. The other arm S7 of the bell crank lever last referred to has engagement through a pin 89 with an actuator in the form of a pendulum link 91, said link being provided with a slot 93 to engage the pin 89. This pendulum link 91 is pivoted at 95 to the knife carrier 7 which, inv this type of machine, is oscillated to cause the knife to out fastenings from a nail strip. The pendulum link will thus, during the operation of the machine,` be reciprocated continuously; and since connection of the pendulum 4link with the arm 87 is made through the slot 93 and pin 89,'the reciprocation of the link will be permitted without. disengagement of said link from the bell crank lever. The slitting knife 21 is recipro cated in a Aslideway in the frame of the machine by a lever 97 pivoted at its lower end at 99 to the frame of the machine and having its upper end extending through a slot in the knife 21. This lever is normally maintained with the knife in a retracted position by a spring 101 connected with the frame of the machine and with an arm 9S of the lever 97` a screw 103 threaded through said arm engaging a portion of the frame so as to serve as an abutment to regulate the distance to which the knife isv retracted.

The lever 97 is also provided with another l at its lower end through the pin 82 vpiece of stock upon the table.

link 91 to engage the projection 107 onthe lever 97 the slitting knife will be actuated. Angular movement ot' the rod 81 to an eX*- tent sutlicient to cause operation of the knife Ll is arranged to occur during the last portion of the ldownward movement of the treadlc Q5, this result being acconiplished by using a spring 83 of the proper tension and by properly arranging the various levers as shown.

It has been stated that one of the features of this invention consists in a construction and arrangement whereby the slitting knife or cutter is caused to enter the under surface of the welt and move obliquely through said welt in such a direction that in securing the welt to the stock by the successive operations of the fastening inserting mechanism each Mingue will, before being secured, override the adjacent portion of the tongue immediately in front of it. In order `to bring about this result, the guideway 15 for the welt B extends in the same general direction as that of the path of the knife but downwardly to meet said path at an acute angle; and in order to insure proper feeding of the welt there may be provided, if required, a guiding device, indicated at 111, which may be of any suitable construction. A heel portion of a sole to which a welt or rand has .thus been attached is shown in Fig. 3,'t-he arrow indicating the direction in which the rand was fed. Considering for example the first two tongues 100 and 200 it will be evident that these tongues were formed by the action of the slitting mechanism in the order named; vThe tongue 100 was therefore secured in place by its respective` fastening while the tongue 200 was being crowded forward by the feed mechanism, with the result that the forward portion of the tongue 200 overrode thc adjacent portion of the tongue 100. And similarly the forward portion of each succeeding tongue overroce thcadjacent portion ofthe next preceding one.

The operation of the vmachine as far as concerns the presentinvention is briefly as follows:-i\ssuming the machine to be in inoperative position with the table 13 lowered` the workman places the sole or other Upon depression of the treadle the table is first raised b v the cam 37 to clamp the stock and the end of the welt between the table and the fccd.roll 11. Further'depression of the treadlc operates the clutch mechanism through the rods 59 and 23 and starts the Y so that ditlicultywould be experienced in.

feeding the welt to the edge a further depression of the treadle renders the slitting I mechanism operative by4 shiftingthe path of v 4 the link 91. As soon'as the curved part of the stock has beendealt with andthe use ofk the slittingmechanism is no longer required', l the treadle is raisedsuiicientlyto remove the path yof the projection'lOQ on the' pendul'111m 91 from the projection on 'the 'lever 97'.v --'l-hereafter th'emachinewillconoperationthe treadle is 'raised,''whereilpon' tinue to.' operate without slitting ther jw'el't until "upon completion ofthe welt 4attaching A* the clutch -will first. be thrown out and thenv thetable lowered for clined sli-ts inthe inner mar completed work,...

Throughout the appended claims' the word welt.v will '-be used "for" convenience should b'e understood that the part-icunature `and function' of thefstrip y'which ttached to the piece o'f stock. is immaterial.
